The Epson 9880 printer provides inconsistent default margins ranging from 3/4" to 1" at top and bottom when printing from ROLLS.

  • Students must pay for an additional 1” (average total default margin) when printing from rolls.
  • It's recommended that students include the desired margins as part of their final image

EXAMPLE:

  • If your image is 18” X 25”, it's recommended that a minimum 1” border should be added on all sides before printing, making the final image size 20” X 27”.
  • If printing on a 24” roll, for example, you will pay for 24” x 28” - ie the width of the roll x the length of the image and including the additional 1" default margin.

  2. Either hang work up to dry, or store it flat and covered to avoid dust

SOFT PROOFING

You can soft proof your image through Photoshop. This allows you to see a better representation of what your image will look like when printed on paper. You can choose the Rendering Intent that will provide the best results for approximating colours that are out of gamut. It is suggested that you toggle between Perceptual Rendering Intent and Relative Colorimetric Rendering Intent.

How to soft proof in Photoshop (Adobe CS4)

  • Go to Proof Setup & choose Custom
  • In Device to Simulate choose profile depending on paper type:

CARRYING AWAY PRINTS

  • Sheets: Bring an acid free flat portfolio to carry away your prints in
  • Rolls: Large prints should be rolled with the image out.  After rolling, the print can be carried away in a large tube
If framing, the print should be laid flat for a few days to discourage curling.
